On 1 June 1960 He (John G. Heyn) and Mr. John. Kannedy of WHD,
nes(nobirk Brown)of OI/OFS, ti. (Robert Bryant)of FI/OPS and Mr(Charles °3
“RI /D moe with Navid M. WILSTED (ps) .03

a ‘WILSTED emphasized that the whole tolephone system in Mexico
“Okt: isiundergoing a reformation. The company Telefonos de Mexico, S.A.,
‘has sub-sontracted this work of cleaning up and reorganizing the phone
eystem: to the independent firm, Intel. They are cleaning up unused and
,Old.lines, putting in new and spare lines, redefining exchange areas,
“lsying. underground cables, etc. Eventually we should be better off be~
‘asuse: there should be more surplus lines. The renovation work has
“hampered much of the LIFRAT work, principally because many of the Lines
‘now are underground and we camot get access. to them before they enter
the central. This is particularly trun with respect to the Czech me
_bassy,: to whose telephone lines we cannot obtain access from the vantage
_Rodnt, wa naw occupy.

“: "3, WILSTRD sedd that we try to keep track of the activities of
- 4 Yntel" but since they seam to attack "Colonias" at random, we have no
; Prior warming of their presenca in a certain arefie

4. In the recent past, Mexico has been using houses for listing
posts for security reasons. ‘e have more control over the access of
phone company inspectors or repairman to houses. I[lowever, under new
regulations, all new apartment budidings must have telephone lines in-
atalled in the buiiding by the phone company during the construction
phage. This means that tho lines and their destination are concealed,
WILSTED preposed that this will mean we can ogain use apartmenta since
we can siphon off a line destined for use by another tenant in such a
way that the phone company cannot trace its destination without tearing
the building apart and we can then install a separate line to the build-
ing and hook. up the subscriber to this line which, if checked, will
belong to a. legitimate subscriber.

5. One system which has been used effectively is to take one-half
of two separate pairs which have one faulty line each. These two half
paixe then form one good pair which we can use.

6. WIISTED explained that it cost about 3000 pesos to get a
regular telephone. This entails the purchase of a telephone company
bond, which later can be sold. |
